Photomicrographs of the intranasal mass. (A) Low-power view showed the mass was mainly infiltrated by small- to middle-size atypical lymphoid cell with admixed inflammatory cells. Perivascular infiltrating and local angioinvasion (*) were observed in the lesion. (B) At higher magnification tumor cells showed irregular nuclear borders and had variable amounts of cytoplasm. Mitotic figures were scattered throughout the lesion (white arrow) (A, HE staining with original magnification ×100; B, HE staining with original magnification ×400).
